Research Papers / a traffic-free zone in downtown Panama city [2]

Downtown Panama City is involved all the areas from Tomba Muerto to Avenida Balboa. These areas (main streets) have always been a traffic problem. The congestion has neither specific hours nor roads.

Can you help me with two chapters related to this topic "A traffic-free zone in downtown Panama city", and give solutions.

*Panama is a small country which has no space for subway, sky train.
